Ariel Helwani discusses Floyd Mayweather pulling out of the fight in Japan, saying Floyd couldn’t have been duped, and is a big miss for his brand.

If you’re a Floyd Mayweather fan, don’t go booking your trip to Japan for the New Year’s Eve return to the ring that he announced Monday at a news conference in Tokyo.
